Question

What is the value of \( K_{sp} \) for saturated solution of \( \text{Ba(OH)_2 \) having pH 12 ?

• A. \( 4 \times 10^{-4} \)
• B. \( 4 \times 10^{-6} \)
• C. \( 5 \times 10^{-6} \)
• D. \( 5 \times 10^{-7} \)

Hint:

For a $AB_2$ type electrolyte, $K_{sp} = s(2s)^2 = 4s^3$, where $s$ is the solubility.

Answer 1

The Correct Option is D
